The University of Missouri campus will be open and classes in session despite the fact that racist death threats have been made against the school’s black students.

The school has been the epicenter of racial tension since the beginning of the Fall semester, culminating with the university’s football team threatening to boycott and Mizzou president Tim Wolfe resigning on Monday, the New York Times reports.

Tuesday night on campus was apparently terrifying. Police arrested a man suspected of making threats to open fire on black students Wednesday, just over a month after the most recent mass shooting on a college campus in Oregon, KSDK reports. Police identified the man as Hunter M. Park, 20.

“I’m going to stand my ground tomorrow and shoot every black person I see,” the suspect wrote on the social media platform Yik Yak on Tuesday night.

Despite the direct threats of gun violence, the university is drawing criticism for holding classes on its regular schedule Wednesday. Some reported seeing the KKK on campus, while students captured video of a man screaming at them on campus about race.
